It's really said to how Miura Haruma is treated, although it's so similar to 1 litres of tears, the difference is the family situation. In 1 litres of tears the family cares so much about her from the beginning to the end, in the hours of my life, he only started to get recognition from his mother after he tells her about his disease. He's best friend stole the girl of his dreams, even though he ended it, the friend shouldn't have been trying to take her away even when he was with her, he's not a true friend. On the other hand, the other friend is. Always been kind to him from the start. The brother is sad also, even though he acts like such a dick, you know the parents pressure on him is taking over his life. He doesn't want to be a doctor and never had a wish for it, he just grew up thinking he HAD to be one for the parents, and it's sad. Anyways, next episode he sees Megumi in his new state, and the fact that she is marrying the back-stabbing friend just shows she's a mean person. To go for his friend just as a rebound and suddenly going to marry him, she never really likes him anyways, just is using him as a rebound. That also differs from 1 litre of tears, the guy who loved her never stopped loving her, and even cared for her when she died.
